TECHNICAL FIELD

[0001] The present application relates to the printing and dyeing technical field, especially to a printing and dyeing wastewater reaction tank. BACKGROUND

[0002] In the traditional industry, printing and dyeing is a relatively heavy pollution industry, and printing and dyeing enterprises will produce a large amount of wastewater in the production process. The wastewater needs to be treated by multiple chemical reactions after primary sedimentation, and then ultrafiltration is performed before being discharged. In this process, a reaction tank is applied.

[0003] For the reaction tank, there are two main ways, the first way is to add a treatment agent to the reaction tank, and the treatment agent is used to treat the wastewater, and the other way is to cultivate anaerobic bacteria in the reaction tank, and the anaerobic bacteria is used to achieve the purpose of treating the wastewater through anaerobic reaction.

[0004] According to the related technology in the above, the inventors believe that the following defects exist: no matter whether the treatment agent is added or the anaerobic bacteria is used for treatment, all the reaction processes need to be realized under the advancement of time. For the reaction tank, with the passage of time, the effective components for treating wastewater in the reaction tank will sink, causing the treatment ability at different heights in the reaction tank to be different, and thus the problem of uneven wastewater treatment exists.

[0039] Specifically, the telescopic frame 22 comprises a primary frame 221, a secondary frame 222 and a tertiary frame 223, the primary frame 221 is in a hollow tubular structure, the cavity in the center of the primary frame 221 is named as a mounting cavity 4, one end of the primary frame 221 is fixed to the crossbeam 21, and the other end is vertically directed to the bottom of the pool body 1. The secondary frame 222 is also in a hollow tubular structure, the secondary frame 222 is sleeved on the primary frame 221, and a primary drive assembly 3 is arranged between the primary frame 221 and the secondary frame 222 to drive the telescopic extension of the secondary frame 222.

[0040] The primary driving assembly 3 comprises a driving screw 31, a driving block 32 and a driving motor 33. The driving screw 31 is rotatably installed in the installation cavity 4 of the primary frame 221, and one end of the driving screw 31 penetrates through the cross beam 21 and is located above the cross beam 21. The driving block 32 has a threaded hole 321 in the center, and the driving block 32 is fixed in the inner cavity of the secondary frame 222, and the driving screw 31 is threadedly connected in the threaded hole 321 on the driving block 32. The driving motor 33 is fixed on the cross beam 21, and a linkage worm gear 311 is fixed on the end of the driving screw 31 penetrating through the cross beam 21. An external thread is formed on the output shaft of the driving motor 33, and the output shaft of the driving motor 33 is engaged with the linkage worm gear 311, so as to control the rotation of the driving screw 31.

[0041] The secondary frame 222 is fixed with two groups of guide rails 226, each group of guide rails 226 has two guide rails, and the two groups of guide rails 226 are symmetrically distributed with the secondary frame 222 as the center, and the guide rails 226 are parallel to the axial direction of the driving screw 31.

[0042] Referring to Figure 2 and Figure 3 , the tertiary frame 223 comprises a base ring 224 and a moving ring 225. The base ring 224 is fixed with a guide strip 10, and the guide strip 10 is engaged with the guide rail 226, so that the base ring 224 is sleeved on the secondary frame 222 and can slide along the length direction of the guide rail 226. The moving ring 225 is composed of two semicircular rings, and the moving ring 225 is embedded in the middle of the base ring 224 and can rotate on the base ring 224 with the secondary frame 222 as the center.

[0043] Referring to Figure 2 and Figure 4 , in order to drive the base ring 224 to slide, the secondary driving assembly 5 is arranged on the secondary frame 222. Specifically, the secondary driving assembly 5 comprises a driving worm gear 51, a driving screw 52 and a driving source 53. The driving worm gear 51 is rotatably installed on the base ring 224 and located between the secondary frame 222 and the base ring 224. The driving screw 52 is rotatably installed on the secondary frame 222 and parallel to the length direction of the guide rail 226, and the driving worm gear 51 and the driving screw 52 are engaged. The driving source 53 can be a pneumatic pump driven by a gas source or a waterproof motor driven by an electric power source. The driving source 53 is fixed on the secondary frame 222, and the output shaft of the driving source 53 is coaxially fixed with the driving screw 52.

[0044] When the driving screw 52 rotates, the driving worm gear 51 must be relatively fixed with the base ring 224 to ensure that the base ring 224 can be driven. Therefore, the positioning assembly 6 for restricting the relative rotation of the driving worm gear 51 and the base ring 224 is arranged on the base ring 224. Specifically, referring to Figure 5 and Figure 6The positioning assembly 6 comprises a positioning cylinder 61 and a positioning block 62. A cylinder hole 227 is formed in the surface of the base ring 224 opposite to the guide rail 226. A positioning hole 228 is formed in the surface of the base ring 224 used to contact the moving ring 225 and located between the moving ring 225 and the guide rail 226. The cylinder body of the positioning cylinder 61 is fixed to the surface of the base ring 224 opposite to the secondary frame 222, and the piston rod of the positioning cylinder 61 penetrates through the cylinder hole 227. The positioning block 62 is in T shape as a whole. One end of the positioning block 62 penetrates into the cylinder hole 227 through the positioning hole 228 and is fixed to the piston rod of the positioning cylinder 61. At this time, a part of the positioning block 62 is still outside the positioning hole 228 and is located between the moving ring 225 and the guide rail 226.

[0045] With reference to Figure 2 and Figure 4 In order to realize the linkage between the driving worm gear 51 and the moving ring 225, an inner ring groove 229 is formed in the inner surface of the moving ring 225 facing the guide rail 226. A transmission tooth 7 is formed in the inner wall of one side of the inner ring groove 229 and is distributed in a ring shape with the secondary frame 222 as the center. A driving gear 8 is fixed to the end of the rotating shaft of the driving worm gear 51 penetrating through the base ring 224, and the driving gear 8 is engaged with the transmission tooth 7.

[0046] When the moving ring 225 needs to be driven to rotate, the positioning block 62 is pressed against the guide rail 226 by the positioning cylinder 61. At this time, the base ring 224 and the guide rail 226 are relatively fixed. When the driving screw 52 rotates, the moving ring 225 can be driven to rotate on the base ring 224 by the driving gear 8. When the base ring 224 needs to be driven to slide, the positioning block 62 is pressed against the moving ring 225 by the positioning cylinder 61. At this time, the relative movement between the moving ring 225 and the base ring 224 is constrained. The engagement relationship between the driving gear 8 and the transmission tooth 7 also makes the rotation of the driving worm gear 51 constrained by the moving ring 225. When the driving screw 52 rotates, the base ring 224 slides along the guide rail 226 under the action of the driving screw 52, thereby realizing the switching between the movement of the base ring 224 and the rotation of the moving ring 225 by the same transmission structure.

[0047] In order to facilitate the installation of the spoiler paddle 23, an extension rod 9 parallel to the extension direction of the extension frame 22 is fixed to the moving ring 225. The spoiler paddle 23 is rotatably installed at the end of the extension rod 9 away from the moving ring 225. The power source 24 is selected to be a pneumatic pump driven by a gas source or a waterproof motor driven by an electric power source. The housing of the power source 24 is fixed to the extension rod 9, and the output shaft of the power source 24 is coaxially fixed with the rotating shaft of the spoiler paddle 23, thereby driving the spoiler paddle 23 to rotate.

[0048] The implementation principle of the printing and dyeing wastewater reaction tank according to the embodiment of the application is as follows: during work, the power source 24 drives the rotating of the turbulence paddle 23, and in the rotating process of the turbulence paddle 23, each structure of the telescopic frame 22 continuously reciprocatingly telescopes to drive the turbulence paddle 23 to make up-and-down lifting movement in the pool body 1, and meanwhile, the movement ring 225 rotates under the driving of the driving gear 8 to drive the turbulence paddle 23 to rotate around the two-stage frame 222, so that the wastewater in the reaction tank flows in all directions under the disturbance of the turbulence paddle 23, the uniformity of the distribution of the treatment agent or anaerobic bacteria in the wastewater is increased, and the consistency of the wastewater treatment is improved.

[0049] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so: equivalent changes made according to the structure, shape, principle of the application should be covered in the protection scope of the application.
